Diopside - doubly terminated gem crystal
stock #21.1-163
Merelani Hills, Lelatama Mountains, Simanjiro District
Manyara Region, Tanzania
3.2 x 1.7 x .9 CM (small miniature/ large thumbnail (toenail))
price: $680


A perfect, complete doubly terminated green Diopside that is fully transparent gem. Of the dozens of these Diopside seen on Mindat none are doubly terminated, this is a very rare example. Some complex geometric internal structures are seen with a close exam as are a few internal Graphite crystals. No damage, and very glassy luster. From Merelani, famed for Tanzanite crystals, these gem Diopsides are much less common on the market, and doubly terminated crystals are very rare in any quality.

Diopside
stock #15.1-674
Orford Nickel Mine, St-Denis-de-Brompton, Estrie
Quebec, Canada
4.3 x 1.3 x .9 CM (miniature)
price: $190
new year 2021

A terminated glassy crystal of Diopside with nice green color on the top. Transparent to translucent, this was in the Warren Johannson collection, a very nice example of a "Nickel" Diopside. There were some large and well-known pale brown crystals found at one time in this locality but very few such complete green crystals. A Canadian classic.

Diopside (Chrome rich crystals)
stock #15.1-672
Orford Nickel Mine, St-Denis-de-Brompton, Estrie
Quebec, Canada
4.5 1.9 x 1.3 CM (miniature)
price: $280
new year 2021

A cluster of yellow-green Diopside crystals with a brilliant luster and sharp form. From the well-known Orford Nickel Mine, this specimen was in the Warren Johansson collection it is a 1960's vintage piece. This is very well defined for this locality where most of the green or "Chrome" crystals are frozen in matrix or are much smaller and incomplete. The locality was also known for some large Diopside crystals with a tabular habit and a brown color. This habit is completely different, transparent to translucent and not often seen.In good condition, one termination is contacted but the others are sharp and well-defined.

Diopside -single crystal
stock #AX-16-548
Orford Nickel Mine, St-Denis-de-Brompton, Estrie
Quebec, Canada
5 x 1.6 x .8 CM (miniature)
price: $230


Exceptional, perfect, partly gemmy and with glassy luster this is a great Orford Diopside. There were larger crystals found years ago but few were so well defined. This has the desirable honey yellow color and looks better in person. A modern classic with top quality, perfectly undamaged and looks fine from every angle.

Diopside -Classic gem crystal with Tremolite
stock #19.1-356
DeKalb, St Lawrence Co.
New York, United States
3.6 x 1.5 x 1.2 CM (small miniature/ large thumbnail (toenail))
price: $575


A fine old DeKalb, New York Diopside crystal with exceptional transparency and color. This has a "crown" of altered Tremolite that adds a nice accent. These encrustations were usually removed by mechanical means but this is still intact and I think gives an nice touch to the crystal. Some typical contacting on the rear and one side, overall the condition is excellent with far better than usual luster.

Diopside- Chromian green with Grossular
stock #18.1-741
Orford Nickel Mine, St-Denis-de-Brompton, Estrie
Quebec, Canada
5.9 x 4.4 x 4.2 CM (cabinet)
price: $375
Spring 2019

The so called Chromian Diopsides from the famed Orford Nickel mine are quite prized. We are told that the color may be due to Nickel and not Chrome but either way these are very attractive and uncommon. This one has unusually fine apple green hue. The largest crystal is 1.7 CM and all are gemmy with very glassy luster. Normally the larger crystals are opaque, and a yellowish to grey color. Such bright green clear crystals are usually only microscopic. Tiny deep green Grossular are also present as are Calcite crystals. The tiny crystals add a lot of sparkle in person.

Diopside with Grossular
stock #18.1-389
Jeffrey Mine, Asbestos
Quebec, Canada
2.6 x 2.2 x 1.8 CM (thumbnail)
price: $70
Late Summer 2018

Mostly a Diopside thumbnail but with some bright orange Grossular tucked between the crystals. A waxy yellow-green color that is not very common at the Jeffrey mine. The central area of the piece is undamaged and well formed, only the outer edge has some chipping. A very affordable but well crystalized piece.

Diopside -large fine single crystal
stock #8.AE-077A
Orford Nickel Mine, St-Denis-de-Brompton, Estrie
Quebec, Canada
7.1 x 2 x 1 CM (cabinet)
price: $450
Spring update

A very big blocky Diopside crystal that is a perfectly formed, has a good color and some translucence. Ex Steve Chamberlain, A. Edwards, and Canning collections, this is remarkably perfect, undamaged and about as clean as can be. Several faces show complex growth patters and have a nice silky luster. Choice for the specie and excellent for the locale.
